EdFairs Asia

We split the experience into two clean entry points, with a single event model underneath.

• /schools — pick an event, choose a booth on the map, add profile and contact details, confirm.
• /visitor — families choose a city and date for events like the Chiang Mai Education Gateway, then register in a few taps.

Same backend, two front doors, so neither audience wades through the other's fields.

For every event we drew a custom venue map built for booth selection. Each booth is an element you can see and click, available and taken states read at a glance, and the moment a booth is reserved its state flips across every open session. The surrounding form stays short (event, school, contact, requirements) so nobody quits halfway through.

This was the hard part. If School A taps booth A61 a split second before School B, School A gets it, and School B sees it vanish and picks another, instantly.
We built a race-safe reservation engine on a modern database, using atomic operations and unique constraints so a booth can only ever be assigned once. The frontend reacts live, so schools watch availability change during the rush. No refreshing, no "sorry, that booth was already taken" emails.

The app runs on Next.js, our default stack for web apps. Server rendering keeps the public sign-up pages fast and search-friendly, assets and caching are tuned for the traffic spike the second registration opens, and the structure extends to new events, cities or countries without a rebuild. Hosting is tuned for low latency across Thailand and the region.

Behind the login sits a CMS built for the EdFairs team: per-event dashboards for schools, visitors, booth occupancy and remaining capacity, searchable and exportable registration lists, and simple control over venues, dates and time slots.
Then we wired in the parts they'd miss: Google Sheets sync for anyone running on-site check-in from a spreadsheet, and automated confirmation emails to schools and visitors. A proper backend and the comfort of spreadsheets, with no double entry.

"Works with five testers" means nothing here, so we simulated hundreds of schools hitting the same event and map at once: rapid booth clicking, form validation under load, and data integrity across the CMS, database and Sheets exports. Each registration window now runs quietly while schools scramble for booths up front.
